The evolution and impacts of Graeme Hugo’s environmental migration research

Drawing on Graeme’s published and unpublished work, as well as his long-term collaborations with two of us, we identify strands of thought that Graeme kept returning to and refining over the course of his career. We trace the evolution of four key points that he often reiterated: (1) The migration-environment relationship is complex and oversimplified; (2) Migration is both a consequence and a cause of environmental change; (3) Migration is just one possible response to environmental change; and (4) Displacement is just one type of migration response. We briefly map his impact on environmental migration scholarship and policy by revealing how key publications have been used in different contexts to shape theory and practice.
